Product Description
The High Efficiency Coating Machine are widely used for coating
various tablets, pills and sweets with organic film,
water-soluble film, slow and controlled release film and sugar
film etc in pharmaceutical, nutrition, foodstuff, and sweets
industries
Working Principle:
The tablets need to be film coated is running a continuous
orbital motion within the closed rotating drum under the action
of a streamline guide plate. During the motion, coating
solution sprays automatically according to the crafts process
and rational crafts parameters, at the same time, hot air is
supplied under negative pressure status, hot air pass through
the tablets and exhaust from the bottom of the tablets layers,
it will make the coating solution sprayed on the tablet surface
dry rapidly and evenly, thus forming a solid and smooth film on
the tablet surface.
Features:
All the operation, including the control of hot air temperature
and adjustment of drum speed, are controlled by PLC and color
touch screen system.
Under the action of the agitator of streamline guide plate
type, the tablets are tumbling smoothly and exchanging
frequently, thus eliminating the tablets to fall from a high
place and colliding, solving the problem of tablets broken and
chipped edge, and improving the rate of finished products. The
narrow guide plate prevent the coating material paste on its
surface, thus saving the coating material and improving the
coating quality.
Adopt the constant-pressure variable peristaltic pump, cancel
the return pipe. The turning radius of the roller varies along
with the pressure change. The supplied coating material and the
spraying volume are balanced automatically; Therefore,
stabilizing the effect of atomization, simplifying the spray
system, preventing the spray gun from plugging-up, and saving
the coating material. Moreover, the cleaning is simple and
there are no dead corners.
The patented spray gun is especially designed and processed for
the film coating machine, atomization evenly and large spraying
area. And the universal adjustable spraying head without dosing
limit. The washing mechanism of the spray gun can prevent the
spraying gun clogging, and make the film coating can proceed
continuously, thus reduced the coating time and saved the
coating material.
